SASI-I-FASTENER.

Specification of Letters Patent.

Patented Feb. 8, 1910.

Application filed September 21, 1909. Serial No. 518,784.

To all whom it may concern:

Be it known that I, AMos KIssINoER, a citizen of the United States, anda resident of the city of Reading, in the county of Berks and State ofPennsylvania, have invented certain new and useful Improvements inSash-Fasteners, of which the following is a specification.

My invention relates to fasteners for the meeting rails of window sashesand my object is to provide a lock of simplified construction and neatappearance, preferably made largely from stamped sheet metal, thestrike-engaging lever of which is adapted to permit the greatestpossible swing about the pivot post in the locking movement so as tomore certainly secure the tight clamping together of the sashes, whileproviding in a simple manner for positively limiting its swing in theunlocking movement.

The accompanying drawings illustrate my invention and the novel featuresare particularly pointed out in the claims.

Figure 1 is a plan view of my sash fastener showing the locking levermoved into engagement with the strike member. Fig. 2 is a sectionalelevation on the line 22 of Fig. 1. Fig. 3 is an end view of the strike;and Fig. 4 is a View of the sheet metal blank from which the strike isformed.

As shown in the drawings 1 is a locking lever formed with a handle 2,strike engaging cam portion 3 and a pivoting hub portion 4:.

5 is a base plate, preferably stamped from sheet metal and provided withscrew-apertures 6 and 7 and a pivot post aperture 8.

The locking lever hub portion 4 is formed with a central bore 9 having abottom coun ter bore 10 for the reception of a spiral spring 11.

12 is a headed pivot post which is passed through bore 9 of the lockinglever and fastened 1n aperture 8 of the base plate 5 to pivotally securethe locking lever 1 to the base plate against the tension of spring 11,which seats on said base plate and against the shoulder formed in thehub portion 4.- by the counter bore 10. The lever 1 as shown anddescribed is thus free to swing on its pivot, the tension of spring 11holding it at rest in any position, and its turning movement be ing onlylimited by contact with the shank portion 15 of the strike member at theeX- tremity of its locking movement, and by a stop against which it willcontact at the eX- tremity of its unlocking movement. This stop, asshown, is preferably provided by using a headed screw 13 in the screwaperture 7 against which the handle 1 strikes and prevents theaccidental projection of the lever over the edge of the sash whenunlocked.

The strike is preferably made from sheet metal cut lnto requisite shapeby suitable dles and bent up into proper form. The blank from which thisstrike is formed is shown in Fig. 4, the shank portion 15 bein bent upat right angles on the dotted line indicated and the upper end 16 turnedover to form a hooked end for engagement with the locking lever cam 3.The portion 17 forms a base plate and is provided with screw apertures18 to secure it to the sash. l have found it desirable both for theappearance of the strike and for the purpose of bringing the shankportion 15 of the locking hook nearer to the screw holes 18 to secure amore vertical strain upon the screws, to cut the base plate 17, as at1919, and bend the shank portion 15 along a line connecting the bottomsof these cuts. This setting in of the shank portion from the outer edgeof the base plate provides sufficient width of the latter to give it afirm foundation on the sash and brings the liftlng strainon the hookedend 16 close to the shank portion and directly over the screws.

I am aware that numerous devices have been designed to lock the meetingrails of window sashes, but my improved construction provides a mosteffective lock of neat appearance and capable of being made up with aminimum amount of labor and expense, while the locking lever 1 beingunlimited in its swing about the pivot post 12 in the locking movement,excepting by contact with the shank of the strike, permits the sashes tobe firmly clamped together by the turning of the lever until the hookedend 16 is tightly engaged, even when an excessive movement is requiredto effect this purpose. And my sheet metal strike member provides for asimple and effective strike of neat appearance and cheap construction.

What I claim is 1. In a sash fastener the combination with a strikemember, of a locking member comprising a base plate, a cam lever havinga pivoting hub seating on said plate and a bottom counterbore in saidhub having a spiral friction spring located therein, and a headed pivotpost for said lever rigidly secured to said plate the movement of saidlever being positively limited in one direction by a stop provided onsaid plate and in the other direction by contact with the shank portionof the strike.

2.111 a sash fastener the combination with a locking member having apivoted cam lever, of a strike member formed of sheet metal and having abase-plate portion and a bent-up shank portion with hookedend to engagethe locking lever, the connect ing bend of said shank portion With thebase-plate being set in from the outer edge of the base plate.

In testimony whereof, I afiix my signature, in the presence of twoWitnesses.

AMOS KISSINGER.
